FLAT BAR GRAVEL REDEFINED
The DSX 1 is the accessible all-rounder in Marin’s flat bar gravel range—perfect for riders who want one bike to handle commutes, fitness rides, and weekend gravel routes. It delivers confident handling, adventure-ready gearing, and a fast-rolling 700c setup—without breaking the bank. Whether you’re new to gravel or just want a capable, fun machine at great value, this is the one.
LIGHTWEIGHT FRAMESET
At the heart of the DSX 1 is a Series 3 6061 aluminium frame with modern gravel geometry, now featuring a UDH (Universal Derailleur Hanger) for improved drivetrain protection and easy replacement, internal cable routing, and wide tyre clearance for up to 45mm rubber. Paired with a full carbon fork and 12mm thru-axles front and rear, it’s responsive and precise on paved climbs, dirt paths, or loose gravel descents.
MARIN QUALITY
Marin has been designing bikes for the everyday explorer for decades, and the DSX 1 continues that legacy. Thoughtful details like rack and fender mounts, disc brake integration, and reliable spec choices make this a bike that’s ready to go the distance—whether you're rolling to work or chasing weekend escapes.
TEKTRO GEMINI 11-SPEED DRIVETRAIN
Smooth, precise, and designed with off-road versatility in mind, the Tektro Gemini 1x11 system features a clutch-equipped rear derailleur and an 11–50T wide-range cassette. It’s made to handle steep climbs and fast descents with consistent chain retention and intuitive shifting
MARIN FULL CARBON FORK
This full-carbon fork is built for smooth, precise handling with thru-axles and flat-mount disc brakes. Its tough-looking legs have three-pack mounts for extra gear and dedicated spots for a front mudguard.
TEKTRO HD-R285 HYDRAULIC BRAKES
Designed specifically for gravel and endurance riding, the HD-R285 brakes offer powerful modulation with a smooth, consistent lever feel. Paired with 160mm rotors, they provide confident braking on everything from city streets to dirt descents.
WTB RIDDLER 700X45MM TYRES
A fast center tread for efficiency and outer knobs for grip—WTB’s Riddler tyres strike the perfect balance for gravel and urban riding. With generous volume and multi-surface traction, they’re ready for pavement, hardpack, and light trail sections.
TUBELESS-COMPATIBLE WHEELS
Built with strength and upgrade potential in mind, Marin’s 21mm internal width rims are tubeless-ready for fewer flats and more control. Forged alloy hubs and thru-axle spacing add durability without weighing you down.
